The distance to the moon is 238,900 miles. How is this expressed in scientific notation?
a. .00238 X 10^5
b. 2.389 x 10^5
c. 2.3 X 105
d. 2.389 x 10-5
Answer:
Answer is b because scientific notation is a variable between 0-10 to the power of a number depending on how many digits it has.
A number from 1-10 in 238,900 miles is 2.389 so the base variable is 2.389. The decimal got moved from 238900. to the left. It moved 5 places.
It went like this;
1 left: 23890.0
2 left: 2389.00
3 left: 238.900
4 left: 23.8900
5 to the left: 2.38900
So the scientific notation is 2.389^5

Josh practices free throws during basketball practice on Monday and Tuesday. On Monday, he attempts 15 free throws and 6 basketballs went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday, what is the minimum number of free throws required on Tuesday to reach his goal?
Answer:
he has to make 12 shots
Step-by-step explanation:
Josh will have to make a minimum of 12 shots to the basket to reach his goal on Tuesday. Basically, 12 shots are 80% of 15 shots he decides to take every Monday and Tuesday.
Baskets are said to be done when the basketball ends up passing through the basket in the opponent's side of the basketball field. However, Josh is practicing his free throws here.Josh has set a goal to himself that at least 80% of his shots should be basket. Considering that he takes 15 throws on Monday the calculation of baskets will be done as below.[tex]\rm Josh's goal= \dfrac{80}{100} x 15[/tex]
So the Josh's required free throws on Tuesday will be,[tex]\rm Josh's\ goal = 12[/tex]
It can be concluded that Josh will have to make at least 12 of his 15 free throws into the basket on Tuesday to achieve his set goal of 80%.Hence, Josh will have to make 12 free throws into the basket on Tuesday to be able to score at least 80% of his free throws as baskets.

If f(x)=2x(With an exponent of 2) -3, find f(-2)
[tex]f\left(x\right)=2x^2-3f ( x ) = 2 x 2 − 3 find f\left(-2\right)f ( − 2 ).[/tex]
Answer:
5
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
f(x) = 2x² -3
f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3
f(-2) = 5
Answer:
f(-2) = 5
Step-by-step explanation:
We just need to substitute x with -2 and simplify.
f(x) = 2x² - 3
f(-2) = 2(-2)² - 3
f(-2) = 2(4) - 3
f(-2) = 8 - 3
f(-2) = 5

A triangular garden has two rock walls meeting at a right angle. The length of one of the walls is 20 feet. Use the image to find d, the length of the other wall.
Step-by-step explanation:
Here you go, I hope this is helpfull
The length of the other side of the wall is √500 ft
Pythagoras theorem
To get the length of 'd', we will use the pythagoras theorem as shown below:
Given the following
Hypotenuse = 30ftAdjacent = 20ftAccording to the theorem;
[tex]h^2=a^2+d^2\\30^2 = 20^2 + d^2\\900 = 400 + d^2\\d^2 = 900 - 400\\d = \sqrt{500} ft[/tex]
Hence the length of the other side of the wall is √500 ft

Sue is offered a job reshelving books in the University of Montana library from noon until 1 p.M. Each Friday. Her reservation wage for this task is $10 per hour. If the library director offers Sue $100 per hour, how much economic surplus will she enjoy as a result of accepting the job? Now suppose the library director announces that the earnings from the job will be divided equally among the 400 students who live in Sue's dormitory. Will Sue still accept? Explain how your answers to parts a and b illustrate one of the incentive problems inherent in income redistribution programs.
Answer:
Step-by-step explanation:
Sue's initial wage per hour = $10
Sue's wage per hour after the increase = $100
a. Economic surplus to be enjoyed = $100 - $10
= $90
Sue would enjoy an economic surplus of $90.
b. No, because in this case the wage per hour for each 400 student would be;
= [tex]\frac{100}{400}[/tex]
= $0.25
= 25 cents
Redistribution of income is the act of equal sharing of wealth among a certain number of people.
The problem here is that Sue would feel cheated with the division of the earnings among 400 students, but very happy when her wages was increased.
Though the income incentive redistribution programs reduce poverty, but it may be unfair.

ldentify the hypothesis of the statement
If the slope of a line is positive, then the line is not horizontal.
A) the line is not vertical
B) the line is not horizontal
C) the slope of a line is positve
D) the slope of a line is negative
Answer:
C the slope of a line is positive
Step-by-step explanation:
Hypothesis: The phrase following the "if" part of a conditional statement. So the answer would be c- The slope of a line is positive.
C) the slope of a line is positive
A conditional statement has two parts: hypothesis (if) and conclusion (then).
We have the given statement as:
If the slope of a line is positive, then the line is not horizontal.
Here, "if" part of a conditional statement is the slope of a line is positive
So, the hypothesis of the statement is the slope of a line is positive
Therefore the correct option is (C).

Plz HELP with a and b I WILL MARK AS A BRAINLIEST IF YOU CAN HELP ME WITH BOTH A AND B PLZZ
Answer:
a) x = 60
b) b = 110
Step-by-step explanation:
A)
2x and 120 are vertical angles.
vertical angles are equivalent.
2x = 120
divide both sides of the equation by 2
2x/2 = 120/2
x = 120/2
x = 60
B)
b + 20 and 130 are on the same side of the line
(I forgot what the math term is, but they're also equal)
b + 20 = 130
subtract 20 from both sides of the equation
b + 20 - 20 = 130 - 20
b = 130 - 20
b = 110
